Understanding Ketchikan’s Seasons
Ketchikan has a highly seasonal tourism industry. Cruise arrivals, tour schedules, accommodation demand, and outdoor activities are concentrated in the warmer months.
The city is also located in the coastal rainforest of Southeast Alaska. Rain is possible throughout the year, including during summer.
Ketchikan Weather by Month
The following figures come from the NOAA 1991–2020 climate normals for Ketchikan International Airport. They describe long-term averages, not a forecast for your specific trip.
| Month | Average High | Average Precipitation |
|---|---|---|
| January | 40°F | 16.17 inches |
| February | 41°F | 11.80 inches |
| March | 44°F | 10.98 inches |
| April | 50°F | 10.25 inches |
| May | 57°F | 8.68 inches |

| July | 65°F | 7.33 inches |
| August | 65°F | 11.30 inches |
| September | 59°F | 14.30 inches |
| October | 51°F | 18.37 inches |
| November | 44°F | 17.07 inches |
| December | 40°F | 16.27 inches |
Temperatures are rounded to the nearest degree. Precipitation includes rain and melted frozen precipitation.
June averages 7.02 inches of precipitation, compared with 14.30 inches in September. Both months can have rainy days, but their long-term rainfall totals differ considerably.
High Season: Mid-June to Mid-August
This is Ketchikan’s busiest main tourism period. Long daylight hours and relatively mild temperatures make outdoor excursions appealing.
- Weather: Average highs climb from approximately 61°F in June to 65°F in July and August. Even warm days can turn cool near the water, and rain remains possible.
- Crowds: Multiple cruise ships may arrive on the same day, bringing large numbers of visitors into downtown Ketchikan and popular excursion areas.
- Costs: Popular accommodations and tours can be in high demand. Compare prices and book important activities early.
- Activities: Fishing charters, kayaking, flightseeing, sightseeing trips, and many seasonal attractions are generally available, subject to operator schedules and weather.
Late May and Early June
Late May and early June offer a useful balance for travelers who want to experience Ketchikan’s scenery and outdoor activities without waiting for the warmest summer temperatures.
- Weather: May averages a high near 57°F, while June averages approximately 61°F. Bring waterproof clothing and layers.
- Crowds: Cruise activity is underway, but the number of passengers varies by date.
- Costs: Some properties and tours may offer different rates from peak summer. Compare actual prices rather than assuming early-season discounts.
- Activities: Many seasonal excursions are operating, though some may have limited departure times.
The landscape is green, spring flowers are appearing, and longer daylight hours make walking and sightseeing easier.
Bear sightings are possible, but visitors planning a trip specifically to watch bears feeding on salmon should generally consider later summer dates.
September
September brings cooler temperatures, increasing rainfall, active salmon runs, and changing seasonal conditions.
- Weather: The average high is approximately 59°F, with average monthly precipitation of 14.30 inches.
- Crowds: Cruise ships continue to visit during September. Some days are busy, while others offer a more relaxed experience.
- Costs: Savings may be available on selected accommodations or excursions, but they are not guaranteed.
- Activities: Fishing, wildlife viewing, hiking, and many excursions may still be available. Operating schedules can become more limited as the season ends.
September can be especially rewarding for travelers interested in salmon, wildlife, misty landscapes, and photography.
However, its higher rainfall average makes waterproof clothing particularly important.
Pro Tip: If you want a quieter September visit, compare individual dates against the official cruise calendar. The number of ships scheduled for a particular day is more useful than simply choosing the second half of the month.
Visiting Ketchikan During the Off-Season
Outside the main tourism period, Ketchikan offers a different experience. The town remains a year-round community, but many businesses serving cruise passengers and summer visitors reduce their hours or close seasonally.
Winter: November Through March
Winter is quieter, darker, and generally less suitable for travelers expecting a full selection of sightseeing excursions.
- Weather: Average highs range from approximately 40°F to 44°F during November through March. Rain, snow, ice, and changing conditions are possible.
- Crowds: Tourism activity is much lower than during the main cruise season.
- Costs: Some accommodations may have lower rates, but available properties and transportation options can be more limited.
- Activities: Local cultural attractions, selected fishing opportunities, and outdoor activities may still be possible. Confirm seasonal opening hours.
Winter hiking requires careful planning because trails may be muddy, icy, snowy, or affected by storms.
The short daylight hours also limit the time available for outdoor exploration.
Northern Lights sightings are possible under suitable conditions, but Ketchikan’s frequent cloud cover and relatively southern location make it a less dependable aurora destination than interior or northern Alaska.
October: Late Fall
October is one of Ketchikan’s wettest months. NOAA records average precipitation of 18.37 inches and an average high near 51°F.
The main cruise season is ending, although some ships may still visit early in the month.
The published 2026 Ketchikan cruise calendar includes calls through October 9. Future seasons may have different schedules.
Many visitor-focused businesses begin reducing operations, and weather can make boat trips, flightseeing, and hiking less predictable.
October is better suited to travelers who are comfortable with flexible plans and limited seasonal services.
April: Early Spring
April brings longer days and gradually warming temperatures. The average high is approximately 50°F, although cold and wet weather remains possible.
Tourism businesses begin preparing for the main season, but availability varies.
The published 2026 cruise calendar included arrivals during April, showing why the cruise season should not be described as beginning on the same date every year.
April can appeal to visitors interested in local life, scenery, and quieter travel rather than a full summer excursion schedule.
How Cruise Ship Schedules Affect the Best Time to Visit
Ketchikan’s crowds depend heavily on the number and size of cruise ships arriving on a particular day.
Downtown locations such as Creek Street, shopping areas, and excursion meeting points may feel considerably busier when several ships are in port.
The City of Ketchikan Tourism Department provides access to official cruise calendars and passenger-capacity information.
Before choosing travel dates:
- Check the published cruise calendar for your travel year.
- Compare the number of ships scheduled on each potential date.
- Look at arrival and departure times, not just ship counts.
- Plan popular downtown attractions for periods when fewer passengers are in town.
- Book important excursions before arrival, particularly on busy cruise days.
Schedules can change, so check again shortly before traveling.
Note: A month with fewer total cruise visits can still contain individual days with heavy passenger traffic. This is particularly relevant when planning a September visit.
Best Time for Wildlife Viewing in Ketchikan
Ketchikan is surrounded by rainforest, coastal waters, streams, and wildlife habitat. Different animals are easier to observe at different times of year.
Bear Viewing
Black bears occur in the Ketchikan area, and salmon streams can attract bears during late summer.
Late July through early September is an attractive period for observing bears feeding on spawning salmon, although timing depends on the location and annual fish runs.
Herring Cove is a well-known local wildlife-viewing area.
Visitors seeking a more organized bear-viewing excursion can also research Anan Creek, which is accessible by boat or floatplane from communities including Ketchikan.
The Alaska Department of Fish and Game’s Anan Creek guide explains seasonal access, viewing opportunities, and permit requirements.
Bear sightings are never guaranteed.
Warning: Never approach or feed a bear. Keep a safe distance, follow viewing-site instructions, and avoid blocking an animal’s route to food or water. Follow Alaska Department of Fish and Game bear-safety guidance when hiking or visiting remote areas.
Salmon Viewing
Watching salmon return to local streams is one of Ketchikan’s memorable seasonal experiences.
Different salmon species return at different times, and the exact timing varies by stream and year.
The ADF&G fish-viewing guide identifies several Ketchikan-area locations:
- Ketchikan Creek: Salmon-viewing opportunities generally occur from July through October.
- Herring Cove: King and silver salmon viewing is associated with July through October.
- Settlers Cove/Lunch Creek: Pink salmon viewing is associated with August and September.
- Ward Creek: Several salmon species may be observed during the summer and fall.
Creek Street is especially popular because visitors can explore the historic downtown area while looking for salmon in the creek below.
Marine Wildlife
Whales, seals, sea lions, bald eagles, and other wildlife inhabit Southeast Alaska’s coastal environment.
Marine wildlife sightings depend on location, food availability, weather, and the particular excursion route.
Summer offers a broad selection of sightseeing and fishing trips that may provide wildlife-viewing opportunities.
Choose tours based on the animals you most want to see, and remember that wildlife encounters cannot be guaranteed.
Best Time to Visit Ketchikan for Fishing
Ketchikan is widely known for salmon fishing, but the right travel dates depend on the species you want to catch.
Marine and freshwater fishing seasons are not identical. Local conditions, fish returns, and regulations also affect opportunities.
King Salmon (Chinook)
King salmon are an important early-season target.
Alaska Department of Fish and Game reports that mature Chinook occur in Ketchikan-area marine waters from late April through June, with peak availability generally in June.
Local hatchery returns and particular fishing locations may provide opportunities later in the summer.
Sockeye Salmon
July and August are useful months to investigate sockeye opportunities, but returns and access vary by location.
Ask local operators which fisheries are suitable for your travel dates.
Pink and Chum Salmon
Mid-July through August is an attractive period for pink and chum salmon fishing in the broader Ketchikan area.
Some runs continue later, depending on the stream and species.
Coho Salmon (Silver)
Late summer and early fall are important periods for coho salmon.
August and September are useful months to consider, although some coho return earlier or later depending on location.
Halibut
Halibut charters commonly operate during the warmer tourism months, particularly from May through September.
Availability depends on the operator, conditions, and applicable fishing regulations.
Before booking, review the ADF&G Ketchikan fishing information and current regulations.
Fishing Regulations: Seasons, bag limits, size restrictions, and harvest rules can change through emergency orders. Check the current regulations for your exact fishing area and species before your trip.
Best Time for Photography and Scenery
Every season offers different photographic opportunities.
Summer: June Through August
Summer brings lush rainforest vegetation, flowers, active wildlife, and long daylight hours.
The additional daylight provides more time to explore and photograph the coastline, mountains, and historic downtown.
Clear days can offer expansive views, but mist and cloud cover are also part of Ketchikan’s landscape.
September
September can provide changing colors among deciduous trees, misty fjords, salmon activity, and softer seasonal light.
The surrounding landscape is dominated by evergreen forest, so fall foliage is generally less extensive than in destinations known for broadleaf forests.
Waterproof protection for cameras and other equipment is particularly useful.
Winter: November Through March
Winter offers stormy skies, occasional snow-covered scenery, quieter streets, and a different view of the coastal rainforest.
Photographers should plan around short daylight hours and changing weather conditions.
Choosing Travel Dates Based on Your Priorities
Budget Travel
If saving money is your main concern, compare late May, early June, and September against peak-summer dates.
Accommodation prices, flights, and excursion rates vary with demand and availability. A shoulder-season trip is not automatically cheaper.
Off-season travel may reduce some lodging expenses, but limited services and transportation options can offset those savings.
Compare the complete trip cost rather than the room rate alone.
Avoiding Crowds
Choose dates with fewer scheduled cruise passengers whenever possible.
Early-season and late-season travel may offer quieter opportunities, but the specific ship schedule is the most useful planning tool.
For visitors arriving independently, overnight stays can also provide time to explore before or after the busiest cruise passenger hours.
Best Weather for Outdoor Activities
June and July offer relatively favorable rainfall averages, while July and August provide the warmest average temperatures.
For hiking, kayaking, sightseeing, and flightseeing, all four summer months can provide worthwhile opportunities.
However, weather-sensitive activities should be scheduled with flexibility.
Overall Best Balance
For many first-time visitors, late May through early June offers an appealing combination of gradually warming weather, increasing daylight, and access to seasonal activities.
Early September is another option, particularly for travelers interested in salmon, wildlife, and late-season scenery.
Choose July or August if warmer temperatures are your leading priority, while remembering that August’s average rainfall is higher than June’s or July’s.
Your ideal travel dates ultimately depend on whether you value weather, wildlife, available excursions, quieter streets, or lower costs most.
Practical Tips for Planning Your Ketchikan Visit
Book Important Excursions in Advance
Popular fishing charters, bear-viewing trips, and Misty Fiords excursions can have limited capacity.
Book activities that are central to your trip before arrival, particularly during summer.
Confirm departure locations, transportation requirements, cancellation policies, and refund terms.
Allow Flexibility for Weather
Ketchikan’s coastal weather can change quickly.
Flightseeing, boating, kayaking, and other outdoor excursions may be delayed, changed, or canceled when conditions are unsuitable.
If an excursion is a major reason for your visit, consider allowing additional time in your itinerary.
Plan Transportation Carefully
Ketchikan International Airport is located on Gravina Island, across Tongass Narrows from the main town.
Passengers use the airport ferry to travel between the airport and the Ketchikan side.
Allow time for the crossing and any onward transportation when arranging flights, accommodation, or tours.
Pack for Rain and Cool Conditions
Useful items include:
- A waterproof jacket with a hood.
- Comfortable waterproof walking shoes.
- Warm layers for boat trips and cooler mornings.
- A small waterproof bag for electronics and valuables.
- Binoculars for wildlife viewing.
- Appropriate footwear and equipment for planned hikes.
Rain protection is useful even during the warmest months.
Explore Beyond the Main Shopping Area
Ketchikan offers more than its downtown waterfront.
Popular attractions include Creek Street, Totem Bight State Historical Park, the Tongass National Forest, and Misty Fiords National Monument.
Misty Fiords is a remote wilderness destination generally accessed by boat or aircraft. Visitors should confirm transportation and tour arrangements before traveling.
The USDA Forest Service provides additional information in its Tongass National Forest Visitor Guide.
